When I try to start my computer I get a message "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key_". This problem started a few days ago after my computer crashed. I have had it up and running for 7 months now with no problems. I bought a drive that was not compatable* with my motherboard when I got the parts, but a friend let me borrow one to install windows 7. I just bought a drive to try and fix the problem and now I can't locate my windows 7 disc. I've checked all cables and unplugged everything that was in a usb slot. I've gone in bios and looked for boot order and the only thing that is trying to launch is my HDD. I'm beginning to think I'm just boned since I can't find my windows 7 disc.
